Dory, the animated surgeonfish created by the Pixar Animation studios, famously suffered from short-term memory loss leading to many adventures. In reality, many fishes have excellent cognitive abilities and are able to learn and retain important information such as the identity of predators. However, if and how cognition can be affected by anthropogenically altered oceanic conditions is poorly understood. Here, we examine the effect of a widely used pesticide, chlorpyrifos, on the retention of acquired predator recognition in post-larval stage of the surgeonfish Acanthurus triostegus...

Traditional stereotypes about sex and gender present men as assertive, aggressive, sexually adventurous, and emotionally restrained, and women as docile, passive, sexually modest, and emotionally sensitive. Past research has shown that such stereotypes impose constraints on heterosexual relationships that decrease sexual satisfaction for men and women. This study examined the impact of traditional sex and gender stereotypes on a sample of 203 behaviorally bisexual men who were in a heterosexual relationship with a woman to whom they did not disclose their same-sex behaviors...

Introduction: Diagnosis of schistosomiasis in travellers is a clinical challenge, since cases may present with no symptoms or a few non-specific symptoms. Here, we report on the laboratory and clinical findings in Danish travellers exposed to Schistosoma -infested water during white-water rafting on the Ugandan part of the upper Nile River in July 2009. Case presentation: Forty travellers were offered screening for Schistosoma -specific antibodies. Serological tests were performed 6-65 weeks after exposure...

Platinum is a precious and versatile metal and has played important roles in various fields of chemistry ranging from functional materials to anticancer drugs and catalysis. This account highlights an adventurous journey of platinum from promoting phosphorescence to catalyzing a C-H functionalization reaction, or you may consider it our research adventure from phosphorescent materials to catalysis. Interestingly, this journey is driven by a series of "bad" reactions, and of course more importantly by our curiosity about the "bad" reactions...

INTRODUCTION: Preceptor development is critical to successful delivery of experiential learning. Although many preceptor development programs exist, a more individualized approach to training is needed. To accomplish this a national preceptor development program should be considered based on the continuing professional development model. A detailed prototype for this program has been described. METHODS: In this final installment of the series, the twelve evidence-based recommendations from the first installment were utilized to construct a prototype for a preceptor development program...

AIMS AND OBJECTIVES: To illuminate how adults with CHD describe themselves in relation to physical activity. BACKGROUND: Several studies have shown that adults with congenital heart disease (CHD) have reduced exercise capacity and do not reach the recommended daily level of physical activity. With this in view, it is of immense importance to investigate how this population experiences physical activity. DESIGN: Qualitative study with semi-structured interviews analysed with qualitative content analysis...

BACKGROUND: Adventure therapy (AT) is a term that includes therapies such as wilderness therapy and adventure-based counseling. With growing empirical support for AT, the diversity of studies make it difficult to attribute outcomes to specific treatment factors. OBJECTIVES: Researchers explored whether AT, often perceived as an alternative therapy, works because of AT's unique components, or whether factors shared by all therapies were responsible. METHODS: A scoping review was undertaken utilizing a search of major databases, unpublished dissertations, and a hand search for direct comparison trials matching AT with another therapeutic intervention...

BACKGROUND/AIM: Trauma is the leading cause of morbidity and mortality in the pediatric population worldwide, and Israel is no different in this aspect. Of these injuries, craniofacial trauma is a significant cause of morbidity in the pediatric population. The high occurrence of pediatric trauma is possibly related to a lower perception for the hazards that surround them, combined with the restless and adventurous nature that is typical of children. The aim was to perform a retrospective, epidemiological study on facial trauma in children examined in the emergency room in order to analyze the different patterns in pediatric maxillofacial trauma, to emphasize this data and educate those involved in preventing and treating children's injuries...

Utilization of energy-rich crop residues by ruminants is restricted by the presence of lignin, which is recalcitrant to digestion. Application of lignin degrading enzymes on the lignocellulosic biomass exposes the cellulose for easy digestion by ruminants. Laccases have been found to be considerably effective in improving the digestibility by way of delignification. However, laccase yields from natural hosts are not sufficient for industrial scale applications, which restricts their use. A viable option would be to express the laccase gene in compatible hosts to achieve higher production yields...

BACKGROUND: Cancer-related fatigue is one of the most distressing symptoms reported by childhood cancer survivors. Despite the body of evidence that regular physical activity helps alleviate cancer-related fatigue, insufficient participation in physical activity is frequently observed among childhood cancer survivors. OBJECTIVES: This study examined the effectiveness of an adventure-based training programme in promoting physical activity, reducing fatigue, and enhancing self-efficacy and quality of life among Hong Kong Chinese childhood cancer survivors...

The structure of RNA has been a natural subject for mathematical modeling, inviting many innovative computational frameworks. This single-stranded polynucleotide chain can fold upon itself in numerous ways to form hydrogen-bonded segments, imperfect with single-stranded loops. Illustrating these paired and non-paired interaction networks, known as RNA's secondary (2D) structure, using mathematical graph objects has been illuminating for RNA structure analysis. Building upon such seminal work from the 1970s and 1980s, graph models are now used to study not only RNA structure but also describe RNA's recurring modular units, sample the conformational space accessible to RNAs, predict RNA's three-dimensional folds, and apply the combined aspects to novel RNA design...

BACKGROUND: The intentional use of illicit drugs for sexual purposes (also known as 'chemsex') is well known within the MSM communities in Malaysia although research in this population is scarce primarily because both drug use and homosexuality are illegal and stigmatised in Malaysia. METHODS: From April to December 2014, interviews were conducted with twenty men (age range 21-43) living in Greater Kuala Lumpur who had sexual intercourse with other men in the past 6 months and who used illicit drugs at least monthly in the past 3 months...

Like many of us who had the great fortune to work with Bill Paul, my science life was immeasurably altered by my interactions with him. Although intimidating at first because of his stature in the immunology world, it was soon clear that he not only truly cared about the specific research we were doing together, but he wished to convey to his trainees an approach to science that was open, always questioning, and infinitely fun. His enthusiasm was infectious and after my training with him, despite stresses due to funding and publishing hurdles, I never regretted the path I took...

Achievements and capabilities influence the self-esteem of skilled adventure athletes. Self-esteem affects individual mental health. Aging commonly reduces adventure capabilities. To avoid loss in self-esteem, aging adventure athletes are forced to adjust their aspirations. Here, I examine this process using participant observation, ethnographic and autoethnographic approaches. The qualitative data for this analysis are derived from 60 years' experience in outdoor adventure activities, and ∼30,000 person-hours of participant observation...
